SPIROIVIETER TOY.

SPECIFICATION forming part of Letters Patent No. 770,494, dated September 20, 1904.

Application filed June 12, 1903. Serial No. 161,221. LNo model.

To aZZ whom it may concern.-

Be it known that I, HENRY G. CADY, a citizen of the United States, and a resident of Pine Bluff, in the county of Jefferson and State of Arkansas, have invented a Spirometer Toy, of which the following is a specification.

This invention is an improvement in spirometers, and has for its object the provision of a simple and inexpensive device which will not only serve the purpose of testing the lungs, but also as a toy, in which latter'capacity it will afford considerable amusement and at the same time encourage its use to advantage in exercising the lungs.

With these objects'in view the invention contemplates the employment of a blowpipe having the usual mouthpiece and serving to conduct the air expelled from the lungs to tubes rotatably mounted on a vertical portion of said blowpipe in connection with a ring having pockets in its inner surface, against the Walls of which the air blown from the curved outer ends of the tubes strike, whereby to cause a rotation of said tubes, the latter carrying figures, which add to the effectiveness of the device as a toy.

The invention consists in the particular construction and arrangement of the parts, all as hereinafter fully described,and specifically set forth in the appended claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a plan view of a spirometer toy constructed in accordance with my invention. Fig. 2 is a vertical transverse sectional view on the line 2 2 of Fig. l.

In carrying out my invention I employ a base-block A as a support for the device and upon this base-block mount a ring B, preferably raised above the block by means of feet 5, the said ring being provided in its inner surface with pockets 5, continuing entirely around the same. In some instances the baseblock maybe omitted and the ring supported by the feet directly on a table. One wall of the pockets is preferably curved, as shown, to present a surface that will be more elfective in turning the tubes.

0 designates a plowpipe or tube which is let into the bottom of the base-block A and at the center of the ring B is provided with a vertical portion C, forming a hollow standard, upon which are rotatably mounted tubes D D. The outer end of the blowpipe or tube C is provided with a mouthpiece c of any desired shape. The tubes D are held in place by a socket c, secured upon the base-block, in connection with a cap f, threaded upon the upper end of the vertical portion C of the blowpipe, the said cap also serving to close the said upper end of the blowpipe. The hollow standard or vertical portion C of the blowpipe is provided with circumferential series of holes 0, which register with the open ings at the inner ends of the tubes D, the latter each having a cylindrical portion (Z, forming a hub by which said tubes are independently and rotatably mounted on the hollow standard. The outer ends of these tubes are curved to one side and reduced in diameter to provide a small outlet (Z, directed toward the curved walls of the pockets in the ring B.

Mounted upon the tubes, near the outer ends thereof, are figures g and h, which may be of an Indian and cowboy, as shown in the drawings, and are arranged so that one appears to be chasing the other as the tubes are rotated. I also purpose to graduate the raised portion 6 of the ring to provide for registering the distance the tubes are rotated, and .consequently the capacity of the lungs of the person operating the device.

The operation of the device will be readily understood, for upon blowing into the pipe C the air expelled by the lungs will pass into the tubes D and, being discharged from the outer ends into the pockets 6 of the stationary ring B, will cause the tubes to rotate on their axes, the disposition of the curved ends of the tubes being such that the said tubes will rotate in the same direction. The tubes are mounted to freely rotate, and it is therefore possible to impart several revolutions to the tubes by a single exhalation. In the present instance the figures are arranged, respectively, so that the Indian appears to be chasing the cowboy. By providing the graduations the fractional partof a revolution may be registered.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. In a spirometer toy, the combination, of a stationary ring having pockets in its inner surface, a blowpipe having a vertical portion at the center of the ring, tubes having cylindrical portions or hubs at one end by which they are independently and rotatabl y mounted on the vertical portion of the blowpipe with their outer ends terminating at the pockets of the stationary ring, said vertical portion of the blowpipe provided with circumferential holes registering with the tubes, as herein shown and for the purpose set forth.

2. In a spirometer toy, the combination, of the base-board A, the stationary ring B supported on said base-board and provided with pockets in its inner surface, the blowpipe 0 attached to the board and having a vertical portion at the center of the ring and its outer end extended and provided with a mouthpiece, the said vertical portion having two sets of apertures 0; the horizontal tubes D each having at one end a cylindrical portion or hub d by which it is independently and rotatably mounted on the vertical portion of the blowpipe with the outer ends of said tubes curved backward and terminating at the pockets in the stationary ring; and the bearings e and f for holding the tubes on the blowpipe; together with the figures g and h fixed to the rotatable tubes to be carried thereby, as herein shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
